I've got centre lock discs on DT Swiss hubs, 220mm front rotor and 200mm rear, they don't move under braking at all - if they did I'd not trust them sufficiently to ride them.
With that said, if you're going to ride them anyway you may as well bond them in I guess. Maybe epoxy though, as the Loctite that I've used breaks down with heat? Bit of a one shot deal, of course.
